I use Basic Alpha Shapes to get boundary points from some 2d points. As shown in attachments, boundary points like a rectangle is what I want to get. But I failed. Through seeing demo about Alpha_shapes_2, I think that I maybe set a wrong Alpha. I hope that you can give me some suggestions so that I can get correct result.
The wrong boundary points is result of the following code.
Thank you, in advance. I will be honored to receive your help.

Try to tune your alpha parameter to better fit your problem:
